+# Changing Dozzle Base
+
+Dozzle by default mounts to "/". This can be changed with the `--base` flag. For example, if you want to mount to "/foobar" then you can use `--base foobar` or the env variable `DOZZLE_BASE`.
+
+::: code-group
+
+```sh
+docker run --volume=/var/run/docker.sock:/var/run/docker.sock -p 8080:8080 amir20/dozzle --base foobar
+```
+
+```yaml [docker-compose.yml]
+version: "3"
+services:
+  dozzle:
+    image: amir20/dozzle:latest
+    volumes:
+      - /var/run/docker.sock:/var/run/docker.sock
+    ports:
+      - 8080:8080
+    environment:
+      DOZZLE_BASE: foobar
+```
+
+:::
+
+Dozzle will be available at [http://localhost:8080/foobar/](http://localhost:8080/foobar/). This option rewrites all assets to `/foobar/{file.path}` and automatically redirects `/foobar` to `/foobar/`.
+
+## Example with proxy
+
+Here is an example with Nginx and proxy Dozzle with a different base:
+
+```conf
+location ^~ /foobar/ {
+    include /config/nginx/proxy.conf;
+    include /config/nginx/resolver.conf;
+    set $upstream_app dozzle;
+    set $upstream_port 8080;
+    set $upstream_proto http;
+    proxy_pass $upstream_proto://$upstream_app:$upstream_port;
+
+    chunked_transfer_encoding off;
+    proxy_buffering off;
+    proxy_cache off;
+}
+```
